Of course, taste is subjective. I will on occasion listen to awful music for the sole purpose of making fun of it. Like Alanis Morrisette. Or that lyrical disaster Bruno Mars. The problem with those types is that they aren't terrible on purpose...like The Offspring. At least the Offspring recognize that they are hilariously poor.

I wouldn't lump Mumford & Sons into all folk rock bands. Even if you're not into it, there's some amazing bands like The Decemberists, Fleet Foxes, and First Aid Kit that sound nothing like them.

There's an entire genre of bands that I call butt-rock. Shinedown, Staind, Three Days Grace, Breaking Benjamin. They started in the early 2000's but sound like the unwanted leftovers of grunge. No soul, no inventiveness, no sense of humor.
